Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00119 | $0.02452 |
| Opus 5.5 | $0.00048 | $0.00981 |
| Sonnet 5.5 | $0.00024 | $0.00490 |
| Haiku 4.5 | $0.00012 | $0.00245 |
Grade A, and why
web-typography scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 28d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Typography (L1 Engineering Floors)
This layer engineers how static text renders in HTML/CSS: hierarchy, measure, leading, scales, font loading, accessibility, language coverage. It supplies floors and working ranges, nothing on the design side. When frontend-ui-ux, /frontend, or impeccable is active, that owner owns the look; this skill defers on identity questions and keeps the engineering side honest. Full uncut source text: references/web-typography-full.md in the repo root.
Layer contract
- This is L1 in a stack: typographic-writing (L0) -> web-typography (L1) -> dynamic-typography (L2) -> genre/deliverable skills (L3).
- This skill defines engineering floors and ranges ONLY.
- A value pinned by a higher layer is MANDATORY where it applies. A genre skill's pinned measure (an exact ch value inside this skill's range) replaces the range outright. Never average, blend, or split the difference between a pin and a range.
- Apply these ranges only to properties no higher layer has pinned.
- Never claim identity or font-choice authority. Asked "which typeface?": route the question to the frontend owner; answer only the mechanical tests a candidate must pass (script coverage, real weights, distinguishable glyphs, license, reliable WOFF2 files).
Workflow
1. Semantic structure first
Before styling, inspect the content model. Prefer elements that express the content:
h1-h6for document hierarchy;pfor paragraphsul,ol,dlfor actual lists and term/value structuresblockquote/q,figure/figcaption,table/th/tdas the content demandscode,pre,kbd,sampfor computational textstrongfor importance andemfor stress, not mere styling
Do not repair an incoherent document outline with CSS. Set document lang; it drives pronunciation, hyphenation, and glyph selection.
2. Typographic roles before sizes
Name the roles first: display/hero, page title, section heading, body, lead, label, metadata, caption, code, numeric. For each role, decide what contrast it needs against its neighbors. Hierarchy can come from size, weight, width, case, spacing, color, or position; push one or two controls, not all of them. A strong hierarchy usually makes fewer distinctions, not more.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

web-typography is a skill published in the GitHub repository EZotoff/ez-omo-config (6 stars, last pushed 2d ago), licensed MIT. It adds 119 tokens to every session and 2,452 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-18.
